Flapless Versus Flap Technique for Evaluation of Crestal Bone Loss and Osseointegration of Dental Implants

this clinical trial was designed to observe the clinical outcomes of techniques of implant installation including flapless and flap techniques about their effect on; osseointegration that measured by checking dental implants stability with resonance frequency analysis device after 6 months of their installation, initial crestal bone loss around the dental implants after 6 months of their installation that that evaluated radiographically and also recording pain perception by the patients within the initial hours and days after implant insertion by both techniques.The patients collected and operated from department of Oral and Maxillofacial surgery, Faculty of Dentistry, Tanta University, Egypt.

Approval of this research was obtained from Faculty of Dentistry, Tanta University Research Ethics Committee (REC). The purpose of the present study was explained to the patients and informed consents were obtained according to the guidelines on human research published by the REC at Faculty of Dentistry, Tanta University.
